Risk factors
By Mayo Clinic staffStevens-Johnson syndrome is a rare and unpredictable reaction. No test is available to help predict who is at risk. Some factors, however, may increase your risk of developing Stevens-Johnson syndrome, including:
- Existing medical conditions. Viral infections, diseases that decrease your immunity, human immunodeficiency virus (HIV) and systemic lupus erythematosus — a chronic inflammatory disease — increase your risk of developing Stevens-Johnson syndrome.
- Genetics. Carrying a gene called HLA-B12 may make you more susceptible to Stevens-Johnson syndrome.
